Hi All,
I have executed the following commands :

# sudo -u zimbra /opt/zimbra/bin/zmprov ma user1@zimbraserver.solutions.com zimbraAccountStatus maintenance

# sudo -u zimbra /opt/zimbra/bin/zmmailbox -z -m user1@zimbraserver.solutions.com postRestURL "//?fmt=tgz&resolve=replace" /tmp/user1.tgz

On executing the above command i received the following error.

ERROR :service.AUTH_EXPIRED(auth credentials have expired)

I am unable to find the reason for this error.

thanks
